I’m curious whether the change in the default value for the mlt.count parameter from 5 in 4.0 to 20 in 4.x is an intentional change or simply a bug that needs to be fixed. I mean, there is no mention in CHANGES.txt or Jira to note the impact on what a user will see.
The change occurred for SOLR-788: https://issues.apache.org/jira/browse/SOLR-788 http://svn.apache.org/viewvc/lucene/dev/branches/branch_4x/solr/core/src/java/org/apache/solr/handler/component/MoreLikeThisComponent.java?r1=1421333&r2=1421332&pathrev=1421333 -- Jack Krupansky
